Worried about him

I posted earlier about wanting to leave my fiance i packed his stuff nd he was suppose to come get it and im worried. Whenever i tried to leave him before i had to talk him out of commiting suicide this is the first time i didnt respond to him at all after i said im done im freaking out hoping he hasnt done anything crazy but then at the same time im trying to tell myself hes fine. Because everytime i stopped him i feel i was lured into feeling bad and taking him back. Nd yes i told his family but they didnt really do much Any of the other times ig they aint think hes serious
